The patient was an 88–year–old woman who had been admitted to the previous hospital with mucous stools and a 1–month history of diarrhea and anorexia. Although the findings of CT suggested intussusception, no clear lesion was noted in the invaginated segment of the bowel. As the intussusception could not be reduced by endoscopy, the patient was referred to our hospital. A mass was palpable around the umbilicus, with tenderness in the area of mass. An emergency laparotomy was performed, which revealed invagination of the ileocecal region up to the middle of the transverse colon. Right hemicolectomy was performed. The excised specimen was treated by injection of 80 mL of formalin fixative from the oral side. After twelve hours, a longitudinal incision was made, and a 35×25 mm 0–Ⅱa lesion was found in the invaginated segment of the bowel, and the histopathological diagnosis was Tis. In adult cases of colon intussusception, more detailed histopathological investigation of the invaginated segment seemingly without lesions, for example, by injection of formalin fixative is useful.
